Glossary

The language of the Lanterns — every term a new reader needs, none of the homework.

Power Ring
The most powerful weapon in the universe — or the most powerful tool, depending on who's wearing it. A power ring converts its bearer's emotion into hard-light constructs, grants flight, protection, and translation, and chooses its wielder itself. Every Corps has its own version.
Power Battery
A ring's charger. Every Lantern carries a personal power battery — usually shaped like a lantern — and must recite their Corps' oath while recharging. A typical charge lasts about 24 hours.
Central Power Battery
The great reservoir of a Corps' light, housed at its homeworld — Oa for the Greens, Qward for the Sinestro Corps, Zamaron for the Star Sapphires, and so on. All rings of that color draw from it.
The Oath
Each Corps has a sworn oath, recited when charging a ring. The words focus the bearer's emotion and bind them to the Corps. The Green Lantern oath is the most famous — "In brightest day, in blackest night…"
Sector
The Guardians divided charted space into 3,600 sectors, each patrolled by two Green Lanterns. Earth sits in Sector 2814 — home to Hal Jordan, John Stewart, Guy Gardner, and Kyle Rayner.
Guardian of the Universe
The diminutive, blue-skinned immortals who founded the Green Lantern Corps billions of years ago from their homeworld of Oa. Ancient, powerful, and famously bad at admitting mistakes.
Emotional Entity
Emotion incarnate — a living being that is a feeling. Each light of the spectrum has one: Ion (will), Parallax (fear), Ophidian (avarice), the Butcher (rage), Adara (hope), Proselyte (compassion), the Predator (love), and the Life Entity (life). Meet them all on the spectrum page.
The Emotional Spectrum
The full range of emotional energy in the DC Universe, made tangible as light. Seven colors from rage to love, with green — willpower — at the center; black (death) and white (life) beyond them all.
Sciencell
Oa's prison for the Corps' most dangerous captives — including, at various times, Sinestro himself and Lyssa Drak of the Sinestro Corps.
Honor Guard
The Green Lantern Corps' elite — its most trusted veterans, assigned anywhere in the universe trouble brews. Guy Gardner led it; Laira served in it.
Book of Oa
The Guardians' great record of the Corps' history, laws, and prophecies — including the forbidden prophecy of the Blackest Night. Kept by Salaak.
Book of Parallax
The Sinestro Corps' dark mirror of the Book of Oa, carried chained to the wrist of its keeper, Lyssa Drak.
Book of the Black
The Black Lanterns' book of prophecy — foretelling the Blackest Night, the War of Light, and the rise of the Third Army.
Starheart
The mystical green flame that powered Alan Scott, Earth's first Green Lantern — wild magic, not Corps technology, and far older than any ring.
Yellow Impurity
The classic weakness. Parallax — the yellow entity of fear — was once imprisoned inside the Central Power Battery, tainting all green rings with a vulnerability to the color yellow. A Lantern had to overcome great fear to push past it. The entity explanation was established in Green Lantern: Rebirth; it is not an event first revealed by Sinestro Corps War. See the Parallax guide for the original identity and later retcon.
Manhunters
The Guardians' first attempt at an interstellar police force — an army of androids that concluded the best way to enforce order was to eliminate all life. They rebelled, and in Sector 666 they committed the massacre that created Atrocitus and the Red Lanterns. A few still operate in the shadows.
